库连接详解:
<%
/*关键字：
import
Class.forName
DriverManager类
Connection接口
Statement接口
ResultSet接口
*/
//①在使用Class.forName之前，应先使用import导入java.sql包
import.java.sql.*;
//②装载驱动
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//③DriverManager［驱动程序管理器］激发getConnection方法，建立与数据库的连接; Connecction对象代表与数据库的连接，Conn为实例Connection对象JSP编程中使用最频繁的接口之一大家一定要掌握（它的方法较多）
String url="jdbc:odbc:conntest";//数据源名字
Connection conn = DriverManager.getConnection(url,"","");
//④Java.sql.Statement提供在基层连接上运行SQL语句，并且访问结果。Connection接口提供了生成Statement的方法。
Statement s = conn.createStatement();
//⑤ResultSet保存着查询的结果集，提供了逐行访问结果的方法
ResultSet rs = s.executeQuery("select * from titles");
